ROLLER COM PRESSOR.

SPECIFICATION forming part of Letters Patent No. 476,233, dated May 31, 1892.

Application filed January 9, 1892. Serial No. 4=l7,533. .(No model.)

To all whom it may concern:

Be itknown that 1, JAMES Ln FEVRE MYERS, of Boston, in the county of Suffolk and State of Massachusetts, haveinvented certain new and useful Improvements in Roller Compressors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvementin roller compressors.

The object is to provide a system of rollers arranged to receive tapering fleshy leaves, so as to yieldingly impinge equally, or nearly so, throughout the length of the leaves, pressing the juice out of them preparatory to stripping and cleaning the fibers.

VVit-h this end in view my invention consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation, and Fig. 2 is a plan View.

A represents a frame of any suitable c011- struotion. In this frame two distinct sets of rollers are journaled, one set preferably in a horizontal plane in fixed journal-boxes and the other set immediately above the latter with their axes in a slightly-inclined plane, so that at one end the rollers in the two sets touch or nearly touch each other, while at the opposite end of the series they are quite a distance apart, and the distance between intermediate rollers varyin g gradually and successively from one extreme to the other.

13 B represent the rollers at one end of the series. These rollers are corrugated and near to each other. C 0' represent the next pair, D D the next, and E E the next, and so on indefinitely, until as many as are needed are employed, they varying-in number, usually, to correspond with the length of the leaves that the machine is designed to operate upon. The rollers O O, D D, and E Eare all plain rollers, and may be of wood, but preferably are sleeved or faced with brass or other noncorrosive material. The j ournal-boxes a of the upper series of rollers are located in elongated slots Z), having spring-cushions back of them, which allow them a gentle yielding upand-down motion with the passage of the leaves, the set-screws c regulating the tension of the springs. The spindles carrying the rollers are each provided with gear-wheels d, and between these pinions e e are meshed, so that the motion of all the rollers in each series is the same. Filling the spaces between the lower rollers are the perforated plates F, which allow the juice as it is squeezed out of the leaves to pass off into a receptacle G beneath. Suitable plates H are preferably located in corresponding position above the perforated plates.

On the shaft carrying the corrugated roller B a gear-wheel f is secured. A pinion g on the main driveshaft meshes with this gearwheel f, and the shaft is driven by a belt through the pulley J. After leaving the rollers the material is carried off on conveyorbelt K.

At the opposite end of the machine the feedloelt L is mounted on the rollers M, the inner one of which is provided with a gearavheelp, which latter is adapted to be engaged by the gear-wheel p on roller N when thelatter is in its lowered or operative position. The roller N is located over its mating roller M, and is mounted in sliding boxes m, seated in the elongated bearings at. These boxes at are connected to the pivoted levers 0 (one on each side) by links 0, and the levers are connected to the movable stop-board O by suitable links. The stop-board and roller N, together with the connecting mechanism, are so arranged that when one is depressed the other is elevated, and hence when the roller N is lowered, so that the gear-Wheel p thereon meshes with the wheel 19' on its mating roller M, the stop-board O is elevated, and hence permits of the passage of the material fed through by the feed-rollers. When the stop-board is in a depressed position, the roller N is elevated, and, since belt L is operated by roller E through chain q, it follows that when roller N is elevated the feed-belt is stopped. WVhen the parts are in this position, thematerial to be operated upon can be evened up against the stop-board.

Having fully described my inventiomwhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a system of eompression-rollers arranged in pairs, the rollers of the several pairs being spaced vertically at different distances apart, of feeding-rollers and a vertically-movable stop-board located between the feeding-rollers and first pair of compression-rollers, substantially as set forth.

2. The combination, with a system of compression-rollers arranged in pairs, the rollers ot the several pairs being" spaced vertically at dlfferent distances apart, of feed-rollers, a stop-board located between the feed-rollers and compression-rollers, and a lever connectlng the stop-board and the driving feed-roller, substantially as set forth.

3. The combination, with a system of compression-rollers arranged in pairs, the rollers of the several pairs being spaced vertically at different distances, of perforated plates located and filling the spaces between the lower rollers and plates located and filling the spaces between the upper rollers, substantially as set forth.

4. The combination, with a series of rollers journaled in fixed boxes in a horizontal plane and a similar seriesin spring-cushioned boxes in an inclined plane, of feed-rollers and a stopboard located between the feed-rollers and compression-rollers, substantially as set forth.

5. The combination, with two series of rollers, one in a horizontal and the otherin an inclined plane, the nearest in the series being corrugated, and gearing for driving and communicating motion of feed-rollers, of a stopboard located between the feed-rollers and compression-rollers and a conveyer-belt, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses. 7
